=head1 NAME

Lab::Moose::Instrument::SCPI::Sense::Function - Role for the SCPI SENSe:FUNCtion subsystem

=head1 VERSION

version 3.900

=head1 DESCRIPTION

This role is intended for instruments which support a single sense function.
The command for setting the function must be SENS:FUNC $function.
Instruments with concurrent sense shell use the Sense::Function:Concurrent
role.

The set sense function is used by other SENSE: roles, like SENSE:NPLC. For
example,

 $source->sense_function(value => 'CURR');
 $source->sense_nplc(value => 10);

will set the integration time for current measurement to 10 power line cycles.

=head1 METHODS

=head2 sense_function_query

=head2 sense_function

Query/Enable the sense function used by the instrument
